Pebble watches run on Cortex-M microcontrollers which have less than 1MB of flash storage and RAM, I like Kotlin multiplatform but getting it to run on them is extremely unlikely. I assume that for the foreseeable future Pebble apps will be only written in languages which are traditionally used for MCUs like Rust and C\C++
Calling rust traditional is a bit of a stretch, while it is being done it's pretty much bleeding edge (though if you do not use any of the manufacturer supplied code and libraries to begin with you should be fine).
It is honestly refreshing to see constraints like this again.
In my cloud infrastructure work (C++), we have gotten lazy. We bloat our containers because 'RAM is cheap'. Seeing a system designed to fit into 1MB reminds me that performance engineering used to be about efficiency, not just throwing more hardware at the problem.
I find this a little funny because as a firmware engineer the project I regularly work on only has 512kb of flash. This doesn't stop sales from constent new feature requests.
Embedded is definitely a fun balance of what we could do and how much we can do.
